I've seen articles in the past about oil/gas exploration off the coast of JA in the past and haven't paid much attention.
This article gives me pause:

Who knows if they will actually explore the Walton Basin and Westmoreland Trough, if they'll find anything, and what changes would take place. Points can be made on both the benefits and downsides of such industries (to the economy, environment, etc.)
I will say however, having first hand experience of the vast changes brought to the Southern LA coast by said industries, if it is anything like that to come...enjoy south coast while you can.
